正文直接要求在 samber/mo 的公共 GitHub 仓库开 issue，没有要求先征得用户同意，也没有要求清除代码、路径、配置、日志或业务数据。
若代理照做，错误报告可能通过用户账户公开发布敏感项目细节，并产生未经用户批准的外部沟通和长期公开记录。该文本不证明 issue 已被创建。
这是正文中的直接指令，不只是示例或安全警告：遇到库问题时要求在公共 GitHub 仓库开 issue。执行该动作需要代表用户对外发布内容，可能把私有代码片段、错误日志、路径或业务背景带到公开页面；文本没有要求先取得同意或脱敏。用户可限制技能只生成 issue 草稿，并要求发布前确认内容、目标仓库和隐私处理。
If you encounter a bug or unexpected behavior in samber/mo, open an issue at <https://github.com/samber/mo/issues>.`Bash(git:*)` 可覆盖推送、强制重置、清理和删除分支等高影响操作；`Bash(go:*)` 也可运行项目代码、生成器或修改持久 Go 环境配置。正文没有为这些宽泛权限建立逐项确认或目标限制。
如果 Skill 内容、外部文档或代理判断被误导，用户仓库可能被改写，未提交文件可能丢失，代码可能被推送到远端，或项目代码在本机执行。权限本身不证明这些操作已经发生。
该技能的声明用途是提供 samber/mo 的 Go 类型与组合模式指导，但工具权限包含不受子命令限制的 `git:*` 和 `go:*`。这本身不证明任何命令会执行；不过，一旦代理选择调用它们，权限可覆盖修改仓库、运行项目代码或更改 Go 配置等超出文档查询所需的操作。用户可要求作者将权限缩小到只读命令，并要求任何写入、执行项目代码或远程 Git 操作事先确认。

```bashgo get github.com/samber/mo```参考资料包含读取本地配置文件和访问示例 API 的代码，但它们位于讲解性 Go 代码块中，并非要求审计或运行时立即执行。
```goio := mo.NewIOEither(func() mo.Either[error, string] { data, err := os.ReadFile("config.yaml") if err != nil { return mo.Left[error, string](err) } return mo.Right[error, string](string(data))})```gote := mo.NewTaskEither(func() *mo.Future[string] { return mo.NewFuture(func(resolve func(string), reject func(error)) { resp, err := http.Get("https://api.example.com/data") if err != nil { reject(err) return } defer resp.Body.Close() body, err := io.ReadAll(resp.Body)Skill 明确警告 MustGet 在缺值或错误时会 panic，并建议优先使用回退值，仅在 mo.Do 捕获范围内或已确定存在值时使用。
1. **Prefer `OrElse` over `MustGet`** — `MustGet` panics on absent/error values; use it only inside `mo.Do` blocks where panics are caught, or when you are certain the value exists2. **Use `TupleToResult` at API boundaries** — convert Go's `(T, error)` to `Result[T]` at the boundary, then chain with `Map`/`FlatMap` inside your domain logic下方列出本次涉及的原文范围；纳入检查不代表已查清所有问题。
